Rear spring Liners

Re: Rear spring Liners

This has been mentioned before, make sure you grind the head of the new centerbolt to match the original bolt. If you install the new tall head centerbolt the rear housing may crack.

Re: Rear spring Liners

I pulled my spring apart this afternoon.

I noticed some very odd streching of the Quanta liners. They had buckling and were streched wider. I purchased a pre-cut liner kit to compare the old and new - all I can say is WOW....

I put mine back togther with the rubber originals and I can say that it was much easier to compress the spring and the liners sit very neatly between the spring leafs.

Only thing I can see to help with the plastic reproductions would be to grease between the liner and leaf. When the spring compresses and decompresses it slides over the liner. Maybe having some lubrication would reduce the friction (and heat generation).

Just an idea.

Bill:

I think that lubrication is one of the functions of the zinc-rich factory coating. I would be concerned that grease will pick up dirt and will harden with time, and make things even more difficult.

Bill, The same thing happened to a set I put on my spring. After a short time, they all buckled up. After removal, I noted that much of the Ikonoclad (sp) had rubbed off the spring.

I figured that the application was either too thick, or I didn't leave it to dry long enough. I chose to strip the Ikonoclad and apply a light grey primer instead and installed new liners. It's been a year and so far so good.

Re: Rear spring Liners

I used the Quanta liners on my '67 seven years ago, and have seen no distortion or deterioration since.

John,

I don't know what made mine get all messed up - but they did.
The picture I attached was taken around 2-3 months back -
when I pulled it apart, it was actually worse.

The liners were pulled and stretched in every direction. Maybe the material that mine (old ones) were made from is different than yours.

Re: Rear spring Liners

Quanta Liners came in the mail today. I'm concerned about them bunching up over time as in the pictures above. Here's a thought...

What do you all think if I use contact cement between the bottom surface of the liner and the leaf below. The shorter leaf above could still slide on the liner but the liner would stay flat on the longer leaf below. Some silicone grease on the top surface of the liner might also help.

Thought & comments appreciated.

Re: Rear spring Liners

I would say do not use contact cement anywhere.....

The upper and lower springs have to be able to move freely over the liner.

I am pretty sure that is why the original liners were made from a pliable rubber compound and also that the liner would stretch as the springs compressed and decompressed.

I think finding a solution that minimizes friction is the best solution.

Re: Rear spring Liners

When I restored my springs I painted both sides and they look like John's. Never had a problem to this point..

Did you use any grease on these rubber liners, that may cause the bunching you are talking about. Petroleum and rubber don't mix well.

I have some powered graphite lube that I use in locks etc. around the house, that really makes thing slippery, just a thought.
